Absorber for a pipe construction or sewer construction and pipe or sewer configuration provided with the absorber

Abstract

An absorber for a pipe or sewer structure has at least one feed connection and at least one return connection. One or more absorber channels connect a feed to a return stub. The absorber channels of the absorber are combined in an absorber channel mat to form a physical unit, and the absorber channel mat is made of a material having flexible properties, at least while it is being laid in the pipe or sewer structure.

1. A pipe or sewer structure, comprising:
 an absorber disposed on a bottom of the pipe or sewer structure in a portion of the pipe or sewer structure to be repaired, said absorber including at least one feed connection and at least one return connection; 
 one or more absorber channels containing water and fluidically connected between said feed connection and said return connection, said absorber channels extending through an absorber channel mat and forming a physical unit, and said absorber channel mat being made of a material having flexible properties at least while said absorber channel mat is being laid into the pipe or sewer structure; 
 a drawable inliner tube formed of a hardening material hardened under compressed air; and 
 said absorber being secured in the portion of the pipe or sewer structure to be repaired by the hardened inliner tube, as a result of, prior to the hardening of the hardening material, positioning said absorber at the portion and drawing the inliner tube over said absorber, such that, upon hardening, said absorber is secured to the pipe or sewer structure by the inliner tube lining the portion and a repair is effectuated. 
 
   
   
     2. The absorber according to  claim 1 , wherein said one or more absorber channels follows a meandering course between said feed connection and said return connection. 
   
   
     3. The absorber according to  claim 2 , wherein said absorber channel mat comprises a central piece with open-ended absorber channel sections extending parallel to one another, and two end pieces connected to said central piece, said end pieces connecting in each case two mutually adjacent open-ended said absorber channel sections, and one of said end pieces having said feed connection and said return connection. 
   
   
     4. The absorber according to  claim 3 , wherein an upper side of said absorber channel mat is corrugated in a region of said absorber channel sections, thereby increasing a surface of the individual absorber channel sections facing towards an interior of the pipe or sewer structure. 
   
   
     5. The absorber according to  claim 1 , wherein said absorber channel sections extend substantially parallel to a longitudinal extent of said absorber channel mat. 
   
   
     6. The absorber according to  claim 1 , wherein said absorber channel sections extend transversely to a longitudinal extent of said absorber channel mat. 
   
   
     7. The absorber according to  claim 1 , wherein said absorber channel mat comprises lips formed laterally at longitudinal sides thereof, said lips facing laterally outward and tapering outwardly. 
   
   
     8. The absorber according to  claim 1 , wherein said absorber mat is formed of at least two interconnected material layers forming therebetween said absorber channel or channels, and wherein connection regions between said two material layers define a separation of said absorber channel or channels. 
   
   
     9. The absorber according to  claim 1 , wherein a material forming an underside of said absorber channel mat has resilient material properties. 
   
   
     10. The pipe or sewer structure of  claim 1 , wherein the absorber channel mat forms part of the inliner. 
   
   
     11. The pipe or sewer structure of  claim 10 , wherein the absorber channel mat is at least one of woven into the inliner and laminated onto the inliner during formation of the inliner. 
   
   
     12. The pipe or sewer structure of  claim 1 , wherein the inliner is used for repairing the pipe or sewer structure. 
   
   
     13. A pipe or sewer structure, comprising:
 an absorber disposed on a bottom of the pipe or sewer structure, said absorber including at least one feed connection and at least one return connection; 
 one or more absorber channels containing water and fluidically connected between said feed connection and said return connection, said absorber channels extending through an absorber channel mat and forming a physical unit, and said absorber channel mat being made of a material having flexible properties at least while said absorber channel mat is being laid into the pipe or sewer structure; 
 an inliner tube formed of a hardening material hardened under compressed air, said inliner securing said absorber to the bottom of the pipe or sewer structure, after the hardening material hardens; and 
 said absorber being drawn into the pipe or sewer structure at the same time as the inliner, prior to hardening of the hardenable material. 
 
   
   
     14. A method for forming a pipe or sewer structure, comprising the steps of:
 positioning an absorber on a bottom of the pipe or sewer structure in a portion of the pipe or sewer structure to be repaired, the absorber including:
 at least one feed connection and at least one return connection; 
 one or more water containing absorber channels fluidically connected between the feed connection and the return connection, the absorber channels extending through an absorber channel mat and forming a physical unit, the absorber channel mat being made of a material having flexible properties at least while the absorber channel mat is being disposed into the pipe or sewer structure; 
 
 drawing an inliner tube formed of a hardening material in the pipe or sewer structure and over the absorber, to locate the absorber between the inliner tube and the pipe or sewer structure; and 
 after the drawing step, hardening the inliner tube under compressed air to secure the absorber in the portion of the pipe or sewer structure to be repaired with the hardened inliner tube to line the portion effectuate a repair.
